    Description / Table of Contents: Properties and Reactions of Substituted 1,2-Thiazetidine 1,1-Dioxides: 2-and/or 4-Silylated 1,2-Thiazetidine 1,1-DioxidesDepending on the reaction conditions and the molar ratio of the reactants, all possible N- and/or C-4 silylated β-sultams 2-11; are prepared starting with 1,2-thiazetidine 1,1-dioxide (1), The 2,3-disubstituted β-sultams 16 and 19 are silylated at C-4. Disilylation is preferred. The X-ray analysis of 2d is reported. Stability and some spectroscopic properties are briefly discussed.
    Notes: Durch Silylierung unter verschiedenen Bedingungen und in Abhängigkeit von den molaren Verhältnissen der Reaktanden können aus 1,2-Thiazetidin-1,1-dioxid (β-Sultam, 1) alle denkbaren an N- und C-4 silylierten Produkte 2-11 erhalten werden. Die 2,3-disubstituierten β-Sultame 16 und 19 werden an C-4 silyliert, wobei Disilylierung bevorzugt ist. Von 2d wird die Struktur durch eine Röntgenstrukturuntersuchung bei -130°C geklärt. Die Stabilität und einige spektroskopische Eigenschaften werden diskutiert.
